How exactly does one tune-up a compression-igniting engine which has no spark plugs and no ignition timing?

For John Voelcker: If memory serves that unreliability was mainly trying to get compression ignition to work when the engine is sucking in air at -30degrees (C or F!).
For Annatar: Well, there is no spark plug (unless you bought one designed to work in the Canadian arctic) but the problem of getting the right amount of fuel to ignite at the correct time replaces the ignition timing tuneup.

What? Either the fuel pump and injectors are working, or they are not. With diesels, that is binary.
